x = - 2 / 3
- 6 x + 7 y = 11
- 6 * ( - 2 / 3 ) + 7 y = 11
12 / 3 + 7 y = 11
4 + 7 y = 11 Subtract 4 to both sides
4 + 7 y - 4 = 11 - 4
7 y = 7 Divide both sides by 7
y = 1
Coordinate x = - 2 / 3 , y = 1
OR
( - 2 / 3 , 1 )
- 6 x + 7 y = 11
- 6 * ( - 2 / 3 ) + 7 y = 11
12 / 3 + 7 y = 11
4 + 7 y = 11 Subtract 4 to both sides
4 + 7 y - 4 = 11 - 4
7 y = 7 Divide both sides by 7
y = 1
Coordinate x = - 2 / 3 , y = 1
OR
( - 2 / 3 , 1 )
